Description

Technical Field

[0001] This utility model relates to the field of experimental technology for liquids containing particles, and in particular to a stratified sampling device for liquids containing particles and an experimental apparatus for liquids containing particles. Background Technology

[0002] In the food industry, the production of dairy products containing particles often employs agitation to disperse the particles within the product. To study the particle dispersion under different agitation parameters, particle stratification experiments are required. After suspending the dairy product in a container under different agitation parameters, the particle content at different liquid levels needs to be counted. However, the number of suspended particles in each region after agitation is currently undetermined, and counting by photographs usually results in significant errors. Furthermore, when applied to liquids containing large particles, the rapid settling of large particles makes sampling difficult, as conventional sampling methods cannot promptly capture all particles from the corresponding region.

[0003] Most existing stratified samplers are typically suitable for soil or liquid stratification sampling, but lack applicability for sampling containing dairy particles. Utility Model Content

[0004] The purpose of this invention is to provide a liquid stratification sampling device and a liquid stratification experimental device containing particulate matter, which can conveniently achieve stratification sampling of liquid containing particulate matter, and has a simple structure and is easy to operate.

[0005] The objective of this utility model can be achieved by the following technical solutions:

[0006] This utility model provides a stratified sampling device for liquids containing particles, including a container with a top opening. The container includes at least two sampling cylinders that can be detachably connected from top to bottom, and a sampling bottom cover. Two insertion holes are symmetrically opened on the side wall of each sampling cylinder. The container has a stirring and suspension state and a stratified sampling state. When the container is in the stirring and suspension state, two sealing elements are provided on the two insertion holes of each sampling cylinder. When the container is in the stratified sampling state, two sieve plates are inserted into the two insertion holes of each sampling cylinder. The two sieve plates can penetrate the two sealing elements and connect with each other. Drainage holes for intercepting particles are opened on the sieve plates.

[0007] In a preferred embodiment of this utility model, the sides of the two sieve plates corresponding to the sampling cylinder that are close to each other are straight edges, and a clearance hole is provided in the center of the straight edge of the sieve plate. When the two sieve plates are joined together, the two clearance holes on the two sieve plates form a stirring rod hole for the stirring rod to pass through.

[0008] In a preferred embodiment of this utility model, the drain hole is an elongated hole, and multiple drain holes are evenly spaced along the length of the straight edge, and the width of the drain hole is smaller than the average particle size of the particles in the liquid containing particles.

[0009] In a preferred embodiment of this utility model, the sealing component is adhesive tape or plastic wrap.

[0010] In a preferred embodiment of this utility model, the bottom cover is a cylindrical structure with an open top, and the sampling cylinder is a cylindrical structure with open ends.

[0011] In a preferred embodiment of this utility model, threaded connections are used between two adjacent sampling cylinders and between the sampling cylinder and the bottom cover.

[0012] In a preferred embodiment of this utility model, a sealing ring is also provided inside the sampling bottom cover.

[0013] In a preferred embodiment of this utility model, the container is a transparent container.

[0014] In a preferred embodiment of this utility model, the container is made of plexiglass.

[0015] This utility model also provides an experimental apparatus for liquid containing particles, including the above-mentioned liquid containing particles stratification sampling device and a stirrer; the stirrer includes a stirring rod and stirring blades provided on the stirring rod, and the stirring rod can extend into the container from the open end of the container so that the stirring blades are located inside the container.

[0016] As described above, the particle-containing liquid stratification sampling device and particle-containing liquid experimental device of this utility model utilize the cooperation of sampling tubes, sealing components, and sieve plates. After the particle-containing liquid is stirred by a stirrer to suspend it in the container, particles in the corresponding area of ​​each sampling tube can be intercepted by inserting sieve plates into each sampling tube. This enables convenient sampling of particles in different liquid level areas after stirring of the particle-containing liquid, solving the problem of difficulty in stratified sampling of particles in particle-containing liquids, especially the difficulty in sampling large particles. It is beneficial for studying the particle dispersion of particle-containing liquids caused by different stirring parameters. Attached Figure Description

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] like Figures 1 to 4 As shown, this application provides a liquid stratification sampling device containing particles, including a container with a top opening. The container includes at least two sampling cylinders 1 that can be detachably connected from top to bottom, and a sampling bottom cover 2. Two insertion holes 11 are symmetrically opened on the side wall of each sampling cylinder 1. The container has a stirring suspension state and a stratification sampling state. When the container is in the stirring suspension state, two sealing elements are provided on the two insertion holes 11 of each sampling cylinder 1. When the container is in the stratification sampling state, two sieve plates 3 are inserted into the two insertion holes 11 of each sampling cylinder 1. The two sieve plates 3 can penetrate the two sealing elements and connect with each other. The sieve plates 3 are provided with drainage holes 31 for intercepting particles.

[0028] The number of sampling bottom covers 2 is one, and the number of sampling cylinders 1 is determined according to needs. During operation, this sampling device should be used in conjunction with a stirrer. Connect each sampling cylinder 1 and sampling bottom cover 2 of the container, and seal each insertion hole 11 with a sealing component to prevent liquid leakage; the stirring blades of the stirrer extend into the container. Fill the container with the liquid product containing particles, start the stirrer according to the set stirring parameters, and observe the suspension state of the particles. When the stirrer reaches the set speed and runs smoothly, insert the two sieve plates 3 corresponding to each sampling cylinder 1 through the two insertion holes 11 on both sides, breaking through the sealing component, into the center of the sampling cylinder 1 to achieve particle interception. Finally, disassemble each sampling cylinder 1 and sampling bottom cover 2 of the container, collect the particles intercepted on the sieve plates 3 in the sampling cylinder 1 at different heights for counting and research. The disassembled sampling cover 2 contains liquid that has been drained through each sieve plate 3 and also contains some particles. The liquid containing particles in the sampling cover 2 can be separated by another sieve plate to trap the particles, so as to conduct corresponding counting studies on the particles in the area corresponding to the sampling cover 2.

[0029] By adjusting different stirring parameters, multiple sets of experiments can be conducted to study the particle dispersion caused by different stirring parameters. These stirring parameters include stirring speed, stirring blade speed, and the distance between the stirring blade and the bottom of the sampling cover 2.

[0030] Therefore, the sampling device of this application, by utilizing the cooperation of sampling cylinder 1, sealing component and sieve plate 3, after stirring the liquid containing particles with a stirrer to suspend the liquid containing particles in the container, can retain the particles in the area corresponding to each sampling cylinder 1 by inserting sieve plate 3 into each sampling cylinder 1; it realizes convenient sampling of particles in different liquid level areas after stirring the liquid containing particles, and solves the problem of difficulty in stratified sampling of particles in liquid containing particles, especially the difficulty in sampling large particles, which is conducive to studying the particle dispersion of liquid containing particles due to different stirring parameters.

[0031] In the specific implementation method, refer to Figure 1 and Figure 4 In the sampling cylinder 1, the two sieve plates 3 have straight edges 32 on their sides closest to each other. A clearance hole 33 is provided at the center of the straight edge 32 of each sieve plate 3. When the two sieve plates 3 are joined together, the two clearance holes 33 on the two sieve plates 3 enclose each other to form a stirring rod hole for the stirring rod to pass through. This clearance hole 33 can be, for example, a semi-circular hole. The two clearance holes 33 can enclose each other to form a circular stirring rod hole, allowing the stirring rod of the agitator to pass through. This facilitates the sieve plates 3 avoiding the stirring rod while ensuring a better fit between the two sieve plates 3, thus better preventing particle leakage.

[0032] The function of the aforementioned sieve plate 3 is to facilitate the draining of liquid in the corresponding area and retain the particles in the area after the liquid containing particles has been stirred and stabilized in the container. The shape of the drain holes 31 can be designed according to actual needs. For example, in an optional embodiment, the drain holes are elongated holes, and multiple drain holes are evenly spaced along the length of the straight edge 32, and the width of the drain holes is smaller than the average particle size of the particles in the liquid containing particles. Since the particle size in the liquid containing particles is basically uniform, ensuring that the width of the elongated holes is smaller than the average particle size of the particles in the liquid containing particles is sufficient to facilitate the draining of liquid and the retention of particles.

[0033] The aforementioned sealing element is mainly used to seal the insertion hole 11 during the stirring process of the liquid containing particles before stratified sampling. The sealing element can be tape, for example, transparent tape can be used to seal the insertion hole 11 from the inside of the container; the sealing element can also be plastic wrap, which is wrapped around the outer wall of the sampling cylinder 1 to seal the insertion hole 11; the sealing element can also adopt other structural methods, as long as it is convenient to seal the insertion hole 11 and can be punctured by the sieve plate 3. This embodiment is only for illustrative purposes.

[0034] The container's cross-sectional shape can be circular, square, or other shapes. For example, in one specific embodiment, the container's cross-sectional shape is circular, and correspondingly, the bottom cover is a cylindrical structure with an open top, and the sampling cylinder 1 is a cylindrical structure with open ends. In this embodiment, for ease of assembly and disassembly, adjacent sampling cylinders 1 and the sampling bottom cover 2 are connected by threads. The threaded design allows for increasing or decreasing the number of sampling cylinders 1 according to different experimental quantities, while also facilitating the assembly, disassembly, and storage of the sampling cylinders 1. Under this connection method, a sealing ring 21 is generally provided inside the sampling bottom cover 2 for secure waterproofing. Of course, the sampling cylinders 1 and the sampling bottom cover 2 can also be assembled and disassembled using a snap-fit ​​structure or other methods; this embodiment is merely illustrative.

[0035] Furthermore, the container is transparent, for example, made of plexiglass, to facilitate observation of the suspension state of the particles during stirring.

[0036] Furthermore, this application also provides an experimental apparatus for particulate liquids, including the aforementioned particulate liquid stratification sampling device and a stirrer. The stirrer includes a stirring rod and stirring blades disposed on the stirring rod. The stirring rod can extend into the container from the open end of the container so that the stirring blades are located inside the container. This experimental apparatus for particulate liquids includes the aforementioned particulate liquid stratification sampling device and has the same advantages.

[0037] The mixer also includes a base and a support frame mounted on the base. A motor is installed on the support frame, and the motor is connected to the stirring rod to drive the stirring rod to rotate the stirring blades. The specific structure of the mixer is existing technology and will not be described in detail here.

[0038] It should be noted that the particulate liquid stratification sampling device and particulate liquid experimental device of this application are not only applicable to particulate dairy products in the food industry, but also to particulate liquids in the pharmaceutical industry, chemical industry or other industries. They can easily realize the stratification sampling of particles, and are applicable to both large and small particles. The structure is simple and the operation is convenient.

[0039] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
